Is it the right molecule?
NMR (nuclear magnetic resonance) confirms the structure: that the compound in the flask is the one intended.
Services · Analytical verification
Analytical verification by NMR and GC-MS in Thailand: is it the right molecule, and how much is there?
Structure confirmed by NMR (nuclear magnetic resonance) and, where the compound suits it, content measured by GC-MS (gas chromatography–mass spectrometry): for molecules we make for you, and as a service for samples you send us.
Tell us what the sample is and what you need to know. We reply with what to send and how, before you send anything.
Analytical verification by NMR and GC-MS
Suits you if
- You need to confirm a compound's structure
- You need to know how much of it is there
- You want a second check on a sample you already have
Evidence, not advertising
What we verify, and how
Every production batch of FreshTrap: structure confirmed by NMR, content measured by GC-MS. Molecules we make for you are checked the same way, as suits each molecule.
Content · GC-MS
How much is there?
GC-MS (gas chromatography–mass spectrometry) measures the content, so the amount of the molecule is measured, not assumed.
Reporting
What comes with the material
A certificate of analysis (CoA) is available on request.
Two different questions, two instruments. Each molecule we make for you is checked the same way, as suits the molecule, with above 99% purity in every batch. Today the GC-MS runs on the instruments of Chulalongkorn and Kasetsart universities.
Limits
When we are not a fit
The limits that apply to every service (quantity, timeline, certifications and regulated manufacturing) are listed once, on our services page.
